MR Information The 3.5 mm LCP Olecranon Plates System has not been evaluated for safety and compatibility in the MR environment. It has not been tested for heating, migration or image artifact in the MR environment. The safety of the 3.5 mm LCP Olecranon Plates System in the MR environment is unknown. Scanning a patient who has this device may result in patient injury.
1 DePuy Synthes 3.5 mm LCP® Olecranon Plates Surgical Technique
3.5 mm LCP Olecranon Plates. Part of the DePuy Synthes locking compression plate (LCP) System.
Features– Anatomically precontoured
– Left and right plates
– Head holes accept 3.5 mm locking screws, and 2.7 mm and 3.5 mm cortex screws
– Shaft holes accept 3.5 mm locking screws and 3.5 mm cortex screws
– Choice of six lengths with 2, 4, 6, 8, 10 or 12 Combi holes in the shaft
– Guide block for easy and correct insertion of proximal screws
Combi holes: combination locking and compression holesThe dual-purpose Combi hole allows placement of conventional cortex screws on one side, or threaded conical locking screws on the opposite side of the same hole.
Fixed-angle stabilityThe locking screws mate with the threaded plate holes to form a fi xed-angle construct.
Unicortical fi xation optionUnicortical locking screws provide stability and load transfer only at the near cortex due to the threaded connection between the plate and the screw. Because the screw is locked to the plate, fi xation does not rely solely on the pullout strength of the screw or on the frictional force between the plate and the bone.

AO PRINCIPLES
In 1958, the AO formulated four basic principles, which have become the guidelines for internal fixation1, 2.

Anatomic reductionFracture reduction and fixation to restore anatomical relationships.
Early, active mobilizationEarly and safe mobilization and rehabilitation of the injured part and the patient as a whole.
Stable fixationFracture fixation providing abso-lute or relative stability, as required by the patient, the injury, and the personality of the fracture.
Preservation of blood supplyPreservation of the blood supply to soft tissues and bone by gentle reduction techniques and careful handling.

Preparation
1Position patient
Place the patient either in the lateral or the prone positionwith the elbow fl exed over a side rest. Depending on thefracture, use a posterior access up to approximately 5 cmdistal from the supracondylar region.
The supine position with the forearm placed across the chest is also an acceptable option, especially with extended approaches to the lateral pillar or column.

Preparation
2Surgical approach
The incision runs posterior from the supracondylar area to a point 4 cm–5 cm distal to the fracture. It can be slightly curved to the radial side to protect the ulnar nerve.
3Reduce fracture and provide temporary fixation
Reduce the fracture directly or indirectly depending on the type of fracture. Ensure that the coronoid is properly reduced before fixation.
Examine the reduction of the coronoid process to determine if it is correct before fixation.
Use Kirschner wires for temporary fixation.

Select a plate length appropriate for the fracture.
Due to varying patient anatomy, slight bending might be necessary. Using bending irons, contour plates as needed.
The triceps tendon may have to be split in order to apply the plate.
Evaluate whether or not the hole in the proximal tab should be used. If necessary, remove the tab.
Precaution: If bending the tab, take care that the screw in the tab does not collide with the other proximal screws.

After adapting the plate, attach the guiding block, drill sleeves and wire sleeve on the proximal part of the plate. Position the plate on the reduced bone, and attach it temporarily with a 3.5 mm cortex screw or push-pull reduction device.
Note: Determine the combination of screws to be used for fixation. If a combination of locking and cortex screws will be used, cortex screws should be inserted first to pull the plate to the bone.

To determine screw length needed, insert a Kirschner wire through the sleeve assembly. Stop when increased resistance from the subchondral bone is felt. Since it may not always be possible to feel resistance, the use of image intensification is recommended. Slide the direct measuring device over the K-wire to determine the length of screw.
Precaution: All three sleeves must be present. The direct measuring device provides an approximate screw length. Screws longer than 30 mm in the proximal part will collide with the shaft screws.

Remove the K-wire and K-wire centering sleeve. Drill through the 2.8 mm drill sleeve and then remove it.
Insert an appropriate length locking screw through the 3.5 mm locking screw sleeve using the StarDriveTM Screwdriver shaft.
Whenever possible, locking screws should be inserted under power using the torque limiting attachment. The audible ‘click’ will notify the surgeon that the maximum torque value has been reached and the power insertion is completed.
After screw insertion using the torque limiting attachment, always check that the screws are fully inserted by hand tightening them.
Precaution: Always use the torque limiter to restrict the maximum torque.

Alternative technique Insert the 2.8 mm threaded drill guide into a locking hole or Combi hole until fully seated. Drill to the desired depth. Remove the drill guide and use the depth gauge to determine screw length. Insert the appropriate screw.

To remove locking screws, unlock all screws from the plate, then remove the screws completely from the bone. This prevents simultaneous rotation of the plate when unlocking the last locking screw.
If the screws cannot be removed with the screwdriver (e.g. if the hexagonal or StarDrive Recess of the locking screw is damaged or if the screws are stuck in the plate), insert the conical extraction screw with left-handed thread into the screwhead, using the handle with quick coupling, and loosen the locking screw by turning it counterclockwise.
